Hack a Day recently posted about a fun little contest, "Slap Hackaday Logo on Something and Win a Trinket". Nothing too creative came to my mind so I decided to try how big logo I can make. After a little bit of thinking I decided to build a flash projector out of few photography equipment; Nikon SB-600 flash, Nikon AF 35-70mm/3.5-4.5 lens and a cheap extension tube set. I opted for the zoom lens so I'm able to adjust the size of the logo a little bit if I want to.

I started by printing out a few different sizes of the logo to a transparency sheet and cut a circle with a 35mm film frame sized hole in the middle from black cardboard. The flange distance of Nikon F mount is 46.5mm (Lens mount, Wikipedia) and by adjusting the order of the extension tube parts I got the distance from the lens mount quite close to 46mm for placing in the cardboard piece with the logo between two of the parts. In this case the right distance from the lens mainly just helps with the focusing because the focus distance scale works the way it should. The lens is attached to the extension tubes and the tube is taped in front of the flash. And of course the logo has to be upside down to get the projected image the right way around.

Time has gone past fast, it's almost 4 years since the last blog update and there has been only a couple of projects I've added during that time. There are a lot of projects to be added on the projects page and at the time of writing this I'm waiting for the DNS updates to propagate to get this new site online.

I finally finished a long delayed project of rewriting the whole website to be much more better to use and to update. The look of the layout is almost unchanged, but I finally moved from a table based structure to a div based and went through all the old CSS files to remove all unused definitions.

Hopefully I'll find some time to start adding all the waiting content on the website as there is a lot of it.

It was a nice sunny day today so me and my friend decided to go and fly a kite. We attached a cheap pen video camera on to the kite to get some video footage from up high. Below is a link to my friend's site where he has a photo of the setup and another video clip.
